We divide 562975 by 3
The aim is to understand the frequency of 3 in 562975.

On to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Let's proceed to step 2:
The number 3 fits into 26 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 2 after subtracting 24 from 26.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Let's proceed to step 3:
3 can be fit into 22 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 187.0
If we take 21 away from 22, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Let's proceed to step 4:
The number 3 fits into 19 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1876.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

On to step 5:
When dividing 17 by 3, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 18765.0
If we subtract 15 from 17, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Going ahead to step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 187658.0
Deduct 24 from 25 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 187658.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 187658.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 187658.33 with a remainder of 0.001.
